  1. 1. Physiology-Guided Machine Learning for Improved Reliability of Non-Invasive Assessment of Pulmonary Hypertension

    Master-uppsats, Linköpings universitet/Avdelningen för medicinsk teknik

    Sammanfattning : Diagnosing pulmonary hypertension (PH) with right heart catheterization (RHC) is associated with a risk for complications and high expenses, leading to late diagnoses [1]. Transthoracic echocardiography can be used to assess non-invasive indicators for PH such as right ventricular systolic pressure (RVSP), which can be estimated by combining the peak tricuspid regurgitation velocity (TRV) with the estimated right arterial pressure (RAP).

  2. 2. Comparison of direct Fick's principle and thermodilution for calculating cardiac output in patients with pulmonary arterial hypertension.Does the assessment of cardiac index and pulmonary vascular resistance differ depending on which method is chosen?

    Master-uppsats, Örebro universitet/Institutionen för hälsovetenskaper

    Författare :Gabriella Persson; [2023]
    Nyckelord :Pulmonary arterial hypertension; cardiac output; direct Fick´s principle; thermodilution;

    Sammanfattning : Pulmonary arterial hypertension (PAH) is an uncommon but serious disease that causes increased pressure in the pulmonary vessels and increased pulmonary vascular resistance (PVR), which in turn leads to right heart failure. At diagnosis, mean pulmonary artery pressure (mPAP) must be >20 mmHg, pulmonary artery wedge pressure (PAWP) ≤15 mmHg and PVR >2 Wood units (WU). LÄS MER

  3. 3. RIGHT VENTRICULAR STROKE WORK INDEX MED EKOKARDIOGRAFI HOS PATIENTER MED PULMONELL ARTERIELL HYPERTENSION, EN JÄMFÖRELSE MED HÖGERSIDIG HJÄRTKATETERISERING.

    Kandidat-uppsats, Malmö universitet/Fakulteten för hälsa och samhälle (HS)

    Författare :Amajla Fatic; [2021]
    Nyckelord :Echocardiography; pulmonary arterial hypertension; right heart catheterization; right ventricular stroke work index; Ekokardiografi; högersidig hjärtkateterisering; pulmonell arteriell hypertension; right ventricular stroke work index;

    Sammanfattning : Pulmonell hypertension (PH) är en sjukdom med flera olika etiologier som bidrar till ett förhöjt tryck i lungkretsloppet. PH definieras som ett medelartärtryck i lungpulsådern   25mm Hg i vila uppmätt vid högersidig hjärtkateterisering (RHC). De olika orsakerna till PH delas in i fem grupper. LÄS MER

  4. 4. Samband mellan gångsträcka, dyspné och desaturation i 6 minuters gångtest hos en grupp individer med pulmonell arteriell hypertension (PAH) - en registerbaserad pilotstudie.

    Magister-uppsats, Uppsala universitet/Åsenlöf: Fysioterapi

    Författare :Kajsa Hedin; [2020]
    Nyckelord :6-minutes walking test; exercise; dyspnea; desaturation; PAH;

    Sammanfattning : Background: Pulmonary arterial hypertension (PAH) is a rare but serious disease with symptoms as dyspnea, fatigue and intolerance to exercise. The treatment is mainly pharmacological with physical exercise as an important complement. The 6 minutes walking test (6MWT) is used today worldwide for assessment and follow-up of the PAH patient.

  5. 5. Testing of micro-fluidic systems for Raman spectroscopic measurements on biological cells

    Kandidat-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Malin Berger; [2018]
    Nyckelord :;

    Sammanfattning : Pulmonary Artery Hypertension (PAH) is a condition that can affect people as a consequence of infections or diseases such as lung disease, high blood pressure or pneumonia. When afflicted by these diseases, low oxygen content in the lung tissue causes the pulmonary arterial soft muscle cells (PASMC) located in the walls of the pulmonary arteries to chronically swell up.
